Miscellaneous

Odd stuff that doesn't fit elsewhere.

Gridwatch
shows you lots of simulated meters. They show the current UK
electricity consumption, and where the power is coming from. Hover over
meters to get more explanation. This is particularly interesting when a
high pressure zone sits over the UK in winter - very cold, and virtually
no power from wind.

Flightradar24
gives information about planes in the air all over the world, in
real time. There's a phone app too.
